DEF CON 34 · United States · 2026
Independent LED/2×3-header SAO source project; physical build and host compatibility unverified
The public narengogi/defcon-34-shitty-add-on repository describes itself only as an SAO for DEF CON 34. Its single commit contains a native KiCad project, board, schematic, Gerber outputs, an archive, and vector artwork; the board source includes DC 34 and narengogi silkscreen text, a 2×3 generic connector, and LED/resistor-labelled source entries. That is enough to preserve an independent, source-only pre-event add-on project whose formal product name is not published. It is not evidence of a fabricated board, a specific SAO version or pinout, working electronics, a compatible host, a DEF CON or BadgeLife relationship, a sale or giveaway, attendee delivery, a credential function, or a reusable image.
People
This is the public GitHub account name shown as repository and initial-commit publisher. It does not identify a real-world person, assign sole design/art/manufacturing authorship, establish DEF CON or BadgeLife affiliation, prove a physical artifact, or grant reuse rights.
SourceThis record makes a minimal but real current source trail discoverable without dressing it up as a finished conference product. The repository publishes design and fabrication-output files rather than a generic idea alone, yet its lack of documentation, licence, release, build evidence, or public event announcement creates unusually sharp provenance limits. Keeping those limits visible is better than silently inferring a finished LED add-on from the repository name.
The commit-pinned source tree contains a native KiCad project, PCB, schematic, Gerber output files, and an archive. Its schematic defines a generic 2×3 connector, LED, and resistor symbols, while the PCB names corresponding connector and LED/resistor source entries and DC 34/narengogi silkscreen. The material does not state component values, connector orientation, SAO version, pinout, voltage/current budget, polarity, protection, display/LED color or behavior, power source, controller, firmware, board revision, assembly configuration, fabrication result, electrical test, host test, safety outcome, or final physical-unit parity.
The reviewed repository contains no firmware, controller source, build instructions, tagged release, binary, programming guidance, update/recovery path, data behavior, security or privacy review, support policy, warranty, or explicit licence. The board files do not justify inferring programmable behavior, a microcontroller, a particular LED effect, or safe modification instructions.
The only project identity published in the repository is its DEF CON 34 SAO description, the repository-derived Shitty Add-On wording, and narengogi/DC 34 text on the source board. The catalogue uses the handle-qualified title solely to index that source trail; it does not assert a formal retail name, real-world identity, maker affiliation, event authorization, or relationship to any other DEF CON 34 add-on.
Source-backed hardware metadata
Structured technical signals seeded from public badge documentation, repositories, schematics, firmware notes, or event evidence. These fields are designed for filtering, API use, repair planning, preservation, and future Companion Gear matching.
narengogi's repository describes an SAO for DEF CON 34 and publishes a KiCad/schematic/PCB/Gerber tree with source-level connector and LED/resistor entries. This classifies an independent electronic add-on source project, not a physical board, an interface-standard claim, a completed build, or an event-issued artifact.
Signal sourceThe repository description calls the project an SAO and its commit-pinned source contains a generic 2×3 connector. It does not identify an SAO version, pinout, orientation, voltage/current limits, protection, safe host connection, or universal compatibility.

Lifecycle
Operational history
The catalogue preserves the exact public event label without presenting this small source project as an official DEF CON item, a confirmed BadgeLife artifact, a completed delivery, or an access credential.
The project remains image-free rather than publishing board previews, vector artwork, Gerber renderings, screenshots, source graphics, synthetic imagery, or an approximate badge image.
The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.
The catalogue retains a concrete design-file trail without representing it as a fabricated, tested, safe, standards-compliant, or plug-and-play accessory.
The entry uses a handle-qualified index title and links the raw source while avoiding invented technical behavior, a formal release, a legal reuse grant, or a stronger creator claim than the evidence supports.
